TYPAE-CWRITING MACHINE.

SPECIFICATION forming part of Letters Patent NoL 608,634-., dated August9, 1898.

A nmiei filed April 5,1893.

To all whom it may concern.-

Be it known that I, STEPHEN MQBALZER, a citizen of the United States,residing at New York, county of New York, and State of New York, haveinvented certain new andjuseful Improvements in Type-WritihgjMachines,fully described and represented in the following specificationand theaccompanying drawings, forming apart "of the same.

This invention relates to type-Writing machines, and especially to thatclass of machines in whichthetype are grouped upon one or more carriersas distinguished from machines in which each type is mountedindependently, the most common form of machines of this class being thatknown as wheel machines, in which the type are placed upon a rotatingcarrier, such as a wheel or segment, and the latter rotated in one orboth directions to position it for the impression of the desiredcharacter, the impression being made either by a hammer or by themovement of the type-carrier against the paper. The machines heretoforeconstructed on this principle have not been found satisfactory inoperation; chiefly on, account of the difficulty of securing accuratepositioning of the type-carrier for the impression of the desiredcharacter and its certain retention in such position during printing,especially at a high rate of speed or after wear of the mechanism byuse.

One of the special objects of the present invention is to provide animproved type-movement for such machines by which the typeoarrier isunder positive control and positively locked in position before andduring the action of the impression mechanism, so that a correctimpression is secured at any rate of speed at which the machine can beoperated.

Vhile the improved type-movement by which the type-wheel is positionedand held during printing-is applicable generally to machines of theclass referred to, whether the impression be produced by the movement ofthe type-carrier against the paper or by a hammer pressing the typeagainst the paper or the paper against the type, it is of especial valueas applied to machines in which the typcrarrier is moved against thepaper Serial No. 469,224. (l lo model) for printing; and a furtherobject of the invention is to providean improved machine of this specialclass. Such machines are es pecially liable to inaccurately position thetypecarrier and make imperfect impression, especially when operated athigh rates of speed, because the type-carrier is liable to be movedbodily out of position before the type-carrier is properly positioned orto yield so as to permit the type-carrier to overthrow in thepositioning operation even with the devices heretofore used for lockingthe typecarrier in position during the impression. This difiiculty isavoided in accordance with the present invention by positively lockingthe type-carrier against bodily movement during the action of thepositioning mechanism. An important improvement is secured also bylocking the key, type-carrier, and positioning mechanism together duringthe impression movement, so that these parts all move together as asingle construction after the type-carrier is positioned. When thesefeatures are combined with the improved type-movement by which thetype-carrier is positioned, the carrier is first brought into and lockedin position for the impression of thecharacter corresponding to the keyactuated, during which time the carrier is positively held againstbodily movement, and then the type-carrier releasedto permit bodilymovement and moved against the paper for printing, While the key,type-carrier, and positioning mechanism are all looked together duringthe bodily movement of the carrier and the type-carrier still locked inposition for the impression of'theproper character. There .arepreferably provided also means by which when any key is actuated all theother keys are locked against movement, and thus held until thetype-carrier and type-movement have returned to normal position.

In connection with the construction. of a machine embodying the mainfeatures of the invention there have been devised also certain specificfeatures of construction and combinations of devices, which inthemselves form parts of the present invention.

For a full understanding of the invention a detailed description of amachine embodying all the improvements in their preferred form will nowbe given in connection with the accompanying drawings, forming a part ofthis specification, and the features forming the invention specificallypointed out in the claims.

In the drawings, Figure 1 is a plan view of the machine. Fig. 2 is asection on the line 2 of Fig. 1. Fig. 3 is ahorizont-al section, on anenlarged scale, taken below the top plate of the machine, the positionof the platen and feed-rack being indicated in dotted lines. Fig. 4 is avertical section on the line 4 of Fig. 3, looking to the rear, with thepaper-carriage. Figs. 5 and 6 are vertical longitudinal sections on theline 5 of Fig. at, showing the parts in different positions, theribbon-movement being omitted. Figs. 7 and 8 are detail plan views ofthe type-movement, corresponding to Fig. 3, but showing the parts indifferent positions. Fig. 9 is a cross-section on the line 9 of Fig. 3,lookingto the left. Fig. 10 is a central section through the wheelframe. Fig. 11 is a detail plan of the ribbon-feed. Figs. 12 and 13 arerespectively an end view and central cross section of the carriagespringconstruction. Fig. 1 1 is a detail hereinafter referred to.

The scale of Figs. 1 and 2 is half size and of the others full size of amachine embodying the invention in convenient form.

The frame of the machine is shown as formed of the base-plate A, the twoside frames B O, supporting the carriage, and a top plate D, mounted onstandards E on the base-plate A, this top plate D supporting thetype-wheel and operating parts therefor and the ribbonmovement andcovering the machine between the carriage and finger parts of the keys.It will be understood, however, that a frame of any other suitableconstruction may be used.

The type-carrier, as shown, consists of a wheel F, which is loose on asleeve 10, extending through slot 11 in the top plate D, this sleeve 10being carried by the wheel-frame, which, as shown, consists of a bar 12,pivotally mounted in a bearing 13, carried by the topplate D, the bar 12being provided with a hollow hub 14, mounted in said bearing, so thatthe bar 12 is supported just below the under side of the top plate D. Ifbut one row of type were to be used 011 the wheel F, it might be mountedrigidly on a shaft carried by the bar 12 and projecting through the topplate D; but it is preferable to use a plurality of rows of type, so asto diminish the positioning movement of the type-wheel, and thetypewheel is shown mounted as usual in such constructions, a shaft 15,by which the typewheel is actuated, passing through the sleeve 10, whichforms a bearing therefor and being provided at the top with a forked arm16, engaging a pin 17, carried by the type-wheel, so that the type-wheelrotates with the shaft 15, while free to slide upon the sleeve 10, thetypewheel being provided with the usual collar 18, engaged by anysuitable devices for shifting the type-whecl to change the row ofcharacters.

The shaft 15 carries at its lower end, below the bar 12,a cross-piece19, to one end of which is pivoted one arm of a three-armed lever to,this lever forming a positioning member, by the movement of which thetype-wheel is rotated into position for the impression of the characterdesired and being provided with two other arms 21 22, extending at rightangles to the arm 20. The lever a is carried by .a rod 0, to which it ispivotally connected at the junction of the three arms 20 21 22, this rodbeing supported by and sliding in brackets 23, depending from the topplate D, the rod 0 being drawn toward the front of the machine andnormally held in this forward position by a spring 2 1, secured to thepin in the top plate D and to the end of the rod 0. The arm 20 of thelever a is connected to the cross-piece 19 by a stud or pin 1 on thecross-piece entering an opening in the arm 20, which is preferably madea little larger than the pin, as shown in Fig. 14, for the purposepresently to be described. The opposite end of the cross-piece 19carries a similar pin 2, entering a long slot in a link 26, which iscarried by and pivotally connected at its opposite end to a rod 1),similar to the rod 0 previously described and mounted in the same mannerin brackets 23, this link forming a stopping member by which thetype-wheel is stopped and held in proper position when positioned by themovement of lever a.

It will be seen that in the normal position of the parts, as shown inFig. 3, the typewheel and shaft are at dead-center to the lever a in theline of bodily movement and also at dead-center relatively to the link26, as the pin 2 is diametrically opposite the pin 1. By the rocking ofthe lever a, therefore, the typewheel and its shaft 10 will be thrownoff the dead-center, and then the wheel, if necessary,

rotated further by the bodily movement ofthe lever, this being permittedby the slot in the link 26, this link serving to stop and hold thetype-wheel in position by the engagement of the pin 2 with the link atone end of the slot, and the link being actuated in accordance with themovement of the lover a and the character to be printed.

The cross-arms 21 22 of the lever a carry at their outer ends pins 34,which are engaged, respectively, by plates 27 28, carried, respectively,by rods (Z c, mounted and sliding in the brackets 23 in the same manneras rods 1) 0, previously described. These plates 27 28 are cut away ontheir inner forward edges so as to first engage, respectively, the pins3 4 on the respective arms 21 22 as the rods d e move rearward in thebrackets 23, and then their reduced portions come in contact with thecentral pin 5 of the lever a,-the plates 27 28 being arranged atdifferent levels, as shown in Fig. 9, so as to permit them to pass eachother, so that either of them may engage the pin 5. It will be seen alsofrom Figs. 5 and 6 that the pins 1 2, arm 20, and link 26 are soarranged that the arm and link IIO are at different levels, and thecross-piece 19 may thus be carried into any position, rotating in.either direction from the normal position, the arm and link passing eachother.

The keys G are pivoted upon a bar H, mounted in the side frames 13 O atthe rear of the machine and are each provided with a depending arm 29,which arms move be tween guides formed of teeth in a plate 30, the keysbeing returned to position by springs 31, connected to the keys andplate. Behind the arms 29 are mounted bails I I K, these bailsconsisting in the preferred form shown of cross-bars 32 in the path ofthe arms 29 and vertical side arms 33, by which the bails are pivoted onthe bar H. The bails I I each extend over one-half the width of themachine, so as to be engaged each by one-half of the keys, while thebail K extends the full width of the machine and is actuated by all thekeys. Near the center of the machine widthwise each of these bails I I Kis connected by links 34 to vertical levers it" 70, corresponding to therespective bails, these levers being pivoted in brackets 36 on thebase-plate A and forked at their upper ends so as to engage pins 6 onthe slidingrods previously described, the levers t' 2" 7t beingconnected, respectively, to rods (Z c b.

It is necessary that the bails I I and the keys G should be soconstructed and arranged that the keys will move the bails I I differentdistances, so as to position the type-wheel for the impression of thecharacter corresponding to the key actuated. This result may be attainedby varying the construction of the different keys or the construction ofdifferent parts of the bails in accordance with the keys, or any othersuitable means may be used for securing this result in connection withthe other features of the invention, but this result is preferablyattained by the 0011- struction shown, by which a very simple, cheap,and efficient construction is provided.

In this construction all the keys are the same in construction, and theproper variation in the movement of the type-wheel is secured byadjusting-screws Z, carried by the bails I I and corresponding to thekeys G, so that by the adjustment of these screws the proper movement ofthe bails may be secured in accordance with the key actuated. In orderto secure the proper movement of the bail K by the different keys, thisbail also is provided with adj ustin g-screws m, similar to screws Z.These adjusting-screws Z or may be held in position when adjusted by anysuitable means, but there is shown a device for this purpose which initself forms a part of the invention. In this construction the arms 32of the bails are cut away so as to form forks through which the screws Z772 pass, and be tween these forks is placed a thin metal plate 37,which rests upon the screws Z m and is pressed down upon said screws bypressurescrews 38, passing obliquely downward through the bars 32, sothat by forcing in these screws the pressure of the plate 37 upon thescrews Z m may be increased and the lat-- ter held firmly in position,while by loosening the screws 38 the pressure of the plate is released,permitting the screws Z m to be adjusted as desired.

The mechanism thus far described secures the positioning of thetype-wheel in accordance with the character to be printed, the lockingof the type-wheel in said position, and the moving of the type-wheel andwheel-frame rearward for the impression. WVith this mechanism ispreferably combined a locking device by. which the wheel-frame is heldpositively in position during the positioning of the type-wheel, and intheconstruction shown this lockin g device serves also to lock the key,type-wheel, and frame and the positioning mechanism together during theimpression movement and to lock all the other keys against movement whenany one of the keys is actuated for printing and prevents the operationof a key until the key previously struck and other parts have returnedto position. In this construction a locking bar or frame L extends thefull width of the bank of keys G and is mounted loosely on a rod 39 atthe base of the machine, so as to swing vertically below the dependingarms 29 of the keys G and the bails I I K. The barL is so formed as toallow it to move upward without engaging the bails, but is provided witha shoulder 7, which normally is just below and to the rearward of therear edges of the arms 29. The bar L is connected by a link 40 centrallyof themachine to a horizontal arm 41 of the bell-crank lever n, mountedloosely on the bar II, another arm 42 of the bell-crank lever extendingvertically and be: ing connected by a link 43 to an arm 44: on the rearof the wheel-frame 12. In the construction shown the arm 42 is connectedto the link 43 by a pin-and-slot connection, so as to allow the arm 42to move rearward withoutmoving the wheel-frame for a purpose presentlyto be described; but it will be understood that this is notessential sofar as the action of the locking device is concerned and any othersuitable form of connection may be used. i

The lower ends of the arms 29 on keys G are curved for a short distancefrom their rear edges 011 a radius struck from the center of the bar IIand then cut on a curve of shorter radius or inclined so as toform acurve or incline of smaller radius or angle, the curve 8, struck on thelonger radius,forming a lockingsurface coacting with the shoulder 7 asthe keys are actuated to lock the bar L against upward movement,

during the positioning operation, and then the curve or incline 8engaging the shoulder and locking the key, carrier-frame, and the bailsand cooperating parts together during the impression movement, the bar Lbeing permitted to rise as the carrienframe moves and thus hold thewheelframe positively against rearward movement rearward, as fullydescribed hereinafter in connection with the operation of the machine.

With the construction thus far described any suitable paper-carriage,platen, and feed therefor may be used. There is shown a simpleconstruction which will be found convenient and efficient and certainspecific features in which form parts of the invention.

The carriage M is supported on front and rear rollers 45 in the frame ofthe machine by bars 16 47, running thereon, the front bar 47 forming therack-bar by which the carriage is fed. The carriage is held firmly inposition while readily removable from the frame by a clip as, secured tothe rear of the frame by a screw 19 and overlapping the bar 16.

- By simply removing the screw a9 and clip L8 the carriage may be takenout.

The carriage M carries the usual paperfeeding roll and pressure-plate 5O51 and the platen h, which in the form shown consists of a metal bar,over which the paper is fed by the roll and plate 51, the paper beingguided as it is moved upward by the rod 53. The carriage is advanced forletter-spacing by a coiled spring, as usual in such constructions, thecarriage being connected by a cord or band 54. to a hollow pulley 0, tothe inside of which is attached aspring p, coiled about the bearing ofthe pulley. A spring construction is provided by which the tension ofthis carriage-feeding spring may conveniently be regulated as desired,which in itself forms a part of the'invention and is clearly shown inFigs. 12 and 13. In this construction the hub 55 of the pulley 0 runs ina hollow hub 56, which extends through and is mounted to rotate in aplate 57, fixed on the frame and carries outside the plate aratchetwheel q and a thumb-piece r. Upon the plate 57 is mounted afinger-lever s, carrying two pawls 58, one of which will engage theratchet-wheel q in each position as the lever is.

rocked, these pawls being so positioned that on each rocking of thelever so as to release one pawl and throw in the other the ratchetwheelwill be allowed to turn one tooth. One end of the spring 19 is attachedto the pulley 0 and the other to the hub 56 on ratchetwheel q, and thepulley is secured in the hub 56 by a screw 59, which forms a bearing forthe pulley. By this construction the spring may readily be wound up asdesired by the thumb-piece r, and in case the spring is too tight theproper tension may readily be secured by releasing the ratchet-wheel qand spring 0 step by step by the lever s.

The construction shown for releasing the paper-carriage step by step forletter-spacing consists of the common fast-and-loose pawl device 60,which is carried by a lever 61, pivoted on the frame of the carriage soas to rock vertically and connected by alink 62 to an arm 63, extendingrearward from the bellcrank amounted on the bar If an d previouslydescribed in. connection with the locking movement,'so that as thebell-crank is rocked rearwardly by the impression movement of thewheel-frame the pawl device is actuated so that a letter-space movementis secured as the wheel-frame returns to position, as well understood inconnection with similar carriage-feeds. It will be understood that anyother suitable rack-releasing device may be used in connection with thecarriage-spring construction.

For word-spacing a space-l tey N is used, which is shown as pivoted atthe base of the machine and connected to the link 40, so that .byactuating this space-key the bell-crank 'lever 77. on shaft 11 is rockedrearwardly and a spacing movement secured, as in the printing operation,the pin-and-slot connection of the arm 42 to the link 43, previouslydescribed, providing for lost motion sufficient to permit this spacingmovement without movement of the wheel-frame.

The shifting devices for moving the typewheel vertically to change thecase may be of any suitable construction. As shown, the collar 18 011the type-wheel is engaged by the forked end of an arm 64, carried by apin 65, moving vertically in a central opening in the hub 1 1 on theframe 12, and this pin is raised and lowered by a bar 66, carried by oneend of a lever 67, pivoted in brackets on the under side of the topplate D and actuated by two keys S S at one side of the machine, twoshifts being used for three rows of characters, as usual in suchconstructions.

Any suitable inking device may be used, either pad or ribbon, but aribbon is preferred, and there is shown a ribbon-feed which will befound simple and efficient and forms a part of the invention. In thisconstruction the type-wheel is partially surrounded by a ribbon-guide68, as usual, and the ribbon-spools R R are placed on the top plate D infront of this guide, these ribbon-spools R B being mounted in anysuitable manner so as to rotate in either direction and being providedwith ratchet-wheels 69 by which they are driven.

The wheel-frame carries a bar 70, extending forward and sliding on thetop plate D, this bar 70 being guided as the wheel-frame moves backwardand forward by a pin 9, passing through a slot in the. bar. At its frontend this bar 7 O carries a pawl-carrier 71, pivoted to swingtransversely to the bar and having at opposite sides pawls If, one ofwhich en gages one of the ratchet-wheels 69 as the bar 70 moves with thewheel-frame, according to the position of the pawl-carrier 71, which isheld in position according to the ratchetwheel to be actuated by notchescut in the pawl-carrier, and a small spring 7 2, entering either of saidnotches according to the position of the pawl-carrier and the spool tobe actuated thereby. The ribbon is thus fed from one spool to the otherby one of the pawls t, and when the ribbon has been thus wound entirelyonto one spool the pawl-carrier 71 is shifted so as to throw the otherpawl into engagement with the ratchet-wheel 69 on the other ribbon-spool and reverse the ribbon, as well understood in suchconstructions.

The operation of the construction will be understood from a briefdescription.

In the normal position of the parts, as shown in Figs. 3 and 5, with nokey depressed, the type-wheel and wheel-frame are in their forwardposition away from the platen 52. The sliding rods 6 c d e are all intheir forward positions, and thebell-crank lever a is in its forwardposition, with the type-wheel at deadcenter relatively to the arm 20,all these parts being held in position by the spring 24. The locking-barL is in its lowest position with the shoulder 7 just below and in frontof the rear edges of the arms 29, and the bails I I K are all intheirforward positions. Assuming that the key actuated operates the bailI and rotates the type-wheel to the left through alarge part of itssemicircumference, as shown in the drawings, the first action of the keyupon the adj usting-screw Z throws the bail I rearward and throughconnecting-rod 34 and lever 7: moves the rod d rearward in the brackets23, so that the rear edge of the outer portion of the plate 27 engagesthe pin 3 on arm 21 and rocks the bell-crank lever a, so as to throw thetype-wheel off the dead-center and into the position shown in Fig. '7,the pin-and-slot connection 1 of the arm 20 to the cross piece 19permitting this movement and preferably being so formed as to allow nolost motion, but secure the continuous movement of the wheel with thelever a. As the type-wheel is thus rotated, the pin 2 in the cross-piece19 moves forward in the slot in the link 26, the rod 1) beingstationary. The rod d has now been advanced so that the inner cut-awayportion of the plate 27 engages the pin 5 at the center of thebell-crank, by which it is connected to the rod 0, and as the movementof the key, bail, and rod d eontinues the bell-crank a is moved forwardbodily to continue the rotation of the typewheel to the left, thebell-crank carrying with it the rod 0 against the tension of the spring24 and the pin 2 continuing to travel back in the slot in the link 26.At the proper time the bail K is engaged by the arm 29 011 the key beingactuated through one of the adjusting-screws m, and this bail is thenmoved backward and through the link 34 and lever it moves the rod 12rearward with the link 26 until the forward end of the slot in the linkengages the pin 2, when the type-wheel is positioned for the impressionof the letter corresponding to the key actuated and locked in thisposition by the pins 1 2, arm 20, and link 26 engaging the cross-piece19 on opposite sides of the axis of the type-wheel and opposing eachother.

In the construction shown, in which the type-wheel is moved against thepaper for printing, the movement of the bails I K and rods (1 b iscontinued after the type-wheel is thus positioned and locked, so as tocarry the type-wheel frame rearward for the impression of the typeagainst the paper on platen h, the rearward movement of both the lever aand link 26 maintaining the positive locking of the type-wheel againstrotation during this movement and assuring a correct impression.

NVith the wheel-frame mounted on a vertical pivot, so as to swing in ahorizontal plane, as in the construction shown, it will be seen that thechange of position of the type-wheel due to the are through which theframe and type-wheel swing for the impression movement is compensatedfor automatically by the lever a and link 26, so as to secure theimpression of the face of the type squarely against the paper.

During the operation of positioning the type-wheel as thus far describedthe locking device for the wheel-frame has operated to hold thewheel-frame positively in position, so that the movements described,although tending to move the type-wheel and wheel frame, have producedno rearward movement of the type-wheel, but only the rotary movementrequisite for positioning it for the impression of the proper character.This result has been attained as follows: As the key G is depressed andthe arm 29 thrown rearward the rear portion 8 first passes over theshoulder 7 and prevents the raising of the locking-bar L until thisportion 8 has passed inside the shoulder and the front portion 8 is inengagement with the shoulder, when the bar is permitted to rise duringthe further movement of the key, the bar still engaging this surface 8,however, so as to permit it to rise only in accordance with the movementof thekey, and thus locking the key, wheelframe, bar, and the bails andother parts of the positioning mechanism together. In the position ofthe type wheel and actuating parts shown in Fig. 7 the projection 29 onthe key G, which is being actuated, is in the posit-ion shown in dottedlines in Fig. 5, and the surface 8 is just about to release the bar L,

IIO

so as to allow the latter to rise for the rearward impression movementof the typewheel. As the movement of the key G and bails I K continuesthe rods cl I) carry the type-wheel and type-frame rearward, the key,wheelframe, and positioning mechanism being locked together by the bar Land the typewheel being positively locked in position for the impressionof the character corresponding to the key actuated, as previouslydescribed, and as the type-wheel moves rearward the bell-crank n isrocked rearward through the link 43 and by the connectingrod 40 raisesthe locking-bar L, which has been released, as previously described, sothat at the time of impression all the parts are brought into theposition shown in Fig. 6.. In this position it will be seen that thelockingbar L has been raised, so as to bring the shoulder 7 in the pathof the rearward movement of the arms 29 on the keys, so that all thekeys are positively locked against movement, and

this locking of the keys continues until the bar L is again lowered.When the impression is made, the key G, previously actuated, is releasedand all the parts returned to their normal position, the key G beingreturned by the spring 3i and the type-wheel and wheelframe beingreturned through bell-crank a, rod Z7, and spring 24-, and the return ofthe type-wheel and wheel-frame returning the bar L to its lowestposition through the connections previously described. The forwardmovement of the rods cl 1), with the wheelframe and bell-crank a, alsoreturns the bails I K through the levers 1' 7c and connecting-rods 34.The feeding movement takes place during the return of the wheel-frame,as previously described,the movement of the Wheelframe in oppositedirections actuating the pawls through the arms 63, link 62, and lever61. The pawlt has been carried back one tooth on the ratchet 69 on oneof the ribbonspools, and on the return of the wheel from theribbon-spool it rotates the ratchet-wheel one tooth and the ribbon isshifted. The parts are now in position for printing another character,and thus the operation is repeated.

In the operation described the bail I has been described as actuatedbefore the bail K and the pin 2 as moving in the slot in link 26 beforethe link is moved; but this is only because the operation selected forillustration is that of positioning the type-wheel for the impression ofa character requiring the rotation of the type-wheel through nearly ahalfcircumfercnce or nearly the largest movement of the type-Wheel. Itwill readily be understood, therefore, by those skilled in the art thatthe bail K will in some cases be actuated before the bail I or I, sothat the link 26 will move forward before the type-Wheel is rotated andthe wheel then be rotated by the movement of bail I or I while themovement of the link 26 continues, the result being the same aspreviously described. The time and amount of movement of the bails I orI and K depend, therefore, upon the position of the character on thetype-wheel corresponding to the key actuated, and the movement of thebails is varied in accordance with the character to be printed and theiraccurate movement secured solely by the adjustment of the screws Z m,the keys G in construction and movement being all the same.

It will readily be understood by those skilled in the art that the meansfor positioning the type-Wheel are of general application in typewritingmachines of the different classes employing a type-wheel and may be usedin machines of other general construction than that shown.

It will be understood that the invention is not to be limited to theexact construction or arrangement of the devices shown, but that manymodifications may be made therein by those skilled in the art withoutdeparting from the invention. it will be understood also that many ofthe features of invention may be used in constructions not employing theother features and that the claims are intended to cover such use.
